The objective of the present study was to evaluate the influence of thrombophilia risk factors on variables of a chromogenic thrombin generation assay (ETP) in a setting with acute deep venous thrombosis (DVT) and non-DVT patients. In 152 outpatients suspected for DVT, the results of thrombophilia investigations were known. In all patients,...

Background: The burden of cardiovascular disease in diabetes mellitus type 2 (DM2) patients is variable. We hypothesize that metabolic syndrome (MS) and low-grade systemic inflammation modify the extent of atherosclerosis in DM2. Methods: Vascular phenotype was determined using the following endothelium-related, hemostatic, and sonographic...

Ischemic stroke is associated with leucocyte activation. Activated leucocytes release elastase, an enzyme that can degrade fibrinogen. Fibrinogen elastase degradation products (FgEDP) may serve as a specific marker of elastase proteolytic activity. In a case-control study of 111 ischemic stroke patients and 119 controls, significantly higher...

Differences in genetic influence on death from CHD between males and females have been reported. Haemostatic factors have consistently been associated with risk for coronary heart disease (CHD), but sex differences in genetic architecture have not been studied. This study in middle-aged twins investigates whether there are sex differences in...

OBJECTIVE - Epidemiological studies suggest that moderate alcohol consumers have enhanced insulin sensitivity and a reduced risk of type 2 diabetes. Adiponectin, an adipocyte-derived plasma protein, has been found to be negatively associated with adiposity and positively associated with insulin sensitivity. Moderate alcohol consumption may...

Combined association and linkage analysis is a powerful tool for pinpointing functional quantitative traits (QTLs) responsible for regions of significant linkage identified in genome-wide scans. We applied this technique to apoE plasma levels and the APOEε2/ε3/ε4 polymorphism in two Dutch twin cohorts of different age ranges. Across chromosome...

Objective-The beneficial effect of dietary fish oil, rich in omega-3 polyunsaturated fatty acids (PUFAs), on cardiovascular disease is multifactorial and may partly rely on their anticoagulant action. We studied how fish oil intake influenced thrombin generation in plasma and which factors were involved herein. Methods and Results-Twenty-five...

The genetic basis of cardiovascular disease (CVD) with its complex etiology is still largely elusive. Plasma levels of lipids and apolipoproteins are among the major quantitative risk factors for CVD and are well-established intermediate traits that may be more accessible to genetic dissection than clinical CVD end points. Chromosome 19 harbors...

Background: Flow mediated dilatation (FMD) of the brachial artery and soluble intercellular adhesion molecule 1 (sICAM-1) are measures of distinct functions of the endothelium, reflecting nitric oxide (NO)-mediated and pro-inflammatory status, respectively. The comparative value of the two measures in relation to cardiovascular risk is unknown....

BACKGROUND: Patients with Type 2 diabetes mellitus have increased levels of hemostatic risk variables for cardiovascular disease, such as fibrinogen, von Willebrand factor (VWF), factor (F)VIIa, d-dimer and plasminogen activator inhibitor-1 (PAI-1). OBJECTIVES: To evaluate the effect of aggressive vs. standard dose atorvastatin on hemostatic...

In most Westernized societies cardiovascular diseases are the leading cause of death over the age of 45 years and one-quarter of these deaths occur in men below the age of 65 years. The haemostasis system has been identified as an important system in cardiovascular disease (CVD). The European Concerted Action on Prevention from Thrombosis by...

In a diet-controlled, crossover trial with 10 middle-aged men and 9 postmenopausal women, baseline concentrations of fibrinogen influenced the magnitude of decrease of fibrinogen after moderate alcohol consumption. The mechanism of reduction is specific for fibrinogen and unrelated to a reduction in C-reactive protein.

Objective: Pentosan polysulphate sodium (PPS), a heparin-like drug, is supposed to be orally applicable. The objective of the present study was to assess the oral bioavailability of PPS. However, since specific assays for PPS do not exist, this was done by using primary and secondary effect parameters. Methods: The study was carried out using a...

OBJECTIVES: We studied the contribution of putative risk genotypes at the angiotensin I-converting enzyme inhibitor (ACE D/D) and plasminogen activator inhibitor-1 (PAI-1 4G/4G) loci to all-cause and cardiovascular mortality in a population-based cohort. BACKGROUND: The ACE D/D and PAI-1 4G/4G genotypes have been consistently associated with...

Recently, a chromogenic kit for determination of plasmin inhibitor activity, Coamatic® Plasmin Inhibitor, has been developed with the aim to increase specificity and to allow application to a wide range of automates. The highly sensitive plasmin substrate S-2403 is used and, to further improve specificity, a low level of plasmin and a short...

The objective of this study was to evaluate the association of factor VII with dietary factors while also considering the R/Q353 polymorphism. Nutrition is an important determinant of coagulation factor VII, which is also genetically determined by the R/Q353 polymorphism. High levels of coagulation factor VII clotting activity (FVII:C) are...

A chromogenic bioimmunoassay method for determination of t-PA activities has been evaluated on plasmas from healthy individuals and from thromboembolic patients. The assay consists of an initial binding and washing step, whereby plasma t-PA is bound to a specific monoclonal t-PA antibody, which is coated on to microplate wells, followed by a...

Increased plasma fibrinogen levels have been identified as a risk indicator for myocardial infarction, stroke, and thrombosis. Both environmental and genetic factors make an important contribution to plasma fibrinogen levels in humans. In the present study we evaluated, in patients with serum cholesterol levels between 4 and 8 mmol/L, the...
